چکیده

زمان تاخیر حوزه آبخیز یک فاکتور مهم در مدلسازی واکنش حوزه آبخیز است. در این مطالعه مدلسازی زمان تاخیر با استفاده از رگررسیون فازی انجام شده است. برای این منظور، داده های بارش - رواناب حوزه آبخیز خانمیرزا جمع آوری و تحلیل شدند. سپس وقایع (9 واقعه) به دو گروه شامل یک گروه برای ساخت روابطی برمبنای رگرسیون فازی و گروه دیگر برای ارزیابی این روابط تقسیم شدند. نتایج بدست آمده از این تحقیق برمبنای معیارهای آماری خطای نسبی و ریشه میانگین مربع خطا نشان دادند که روابط جدید توسعه یافته برمبنای رگررسیون فازی نسبت به دیگر روابط موجود برای محاسبه زمان تاخیر مناسب تر هستند.
